To all whom it may come m: Be it known that I, LEO M. EVANS, a citizen of the United States, residing at Salt Lake City, in'the county of Salt Lake and State of Utah, have invented certain new and useful improvements in Tire Clamping and Turning Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in tire clamping and turning devices, the main object. of the present invention being the provision of a device of the, above character whereby an automobile tire casing can be readily clamped into position and turned inside out so that the interior of the casing can be inspected for defects or repaired. 1

Another object of the present invention is the rovision of a tire clamping and turning device whereby tires of different sizes can be readily placed in position upon the device and turned inside out for thepurpose of repairing the interior of the tire casing.

.A further object of the invention is the rovision of a-tire clamping and turning device wherein the use of compressed air is utilized for operating a movable plunger head and detachable hook members disposed at right angles to the plurfgerhead and adapted for ready engagement with the heading of a tire moved from place to place. 4 7

With the above and other objects in view the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and s own in the accompanying drawings in which:

F i 7 is an end elevation fof thejhooli mem rs, and r I i .I'

. Fig. 8 is a transverse section taken on the line88ofFig.6. 1:

A frame structure adapted to' be fixedly supported upon any suitable floor or other foundation comprises a base member 1 hav ing secured. to the upper face thereof a plate W 2, said base member having, preferably, a central space 3 beneath the plate 2. Mounted upon, the plate 2, over the'space'3, is a guide member comprising, in the embodi merit shown, a cylinder 4:. Secured to the .7 cylinder'd, preferably at the top thereof, is a transverse supportin member or bar conslsting, preferably, 01 a channel iron 13 Y disposed with its flanges extending downward and secured on top of the cylinder by "355 stay rods 14 the lower ends of-whichiare anchored to the-plate 2 while the upper ends project through-the web of the iron 13 and receive nuts 15.. f -Wi'thin the cylinder 4: is a piston 5 to which is connected a suitable rod 6 extending upward through the member l3,"guided I snugly through said member. and through the head of the cylinder. On the upper end of the rod 6 there may be a removable manat drel or contact block which, as shown, is convexly curved longitudinally and transversely thereof, said block being of greater dimension in one direction than in the other,

by preference,. in order .to permit exposing ea in raise the block 7. In the preferred eznbodimentthe pipe 9 is connected with an upright pipe 16 having an inflating valve 11 at the. upper end which may be connected the to any suitable source of air under pres sure. in order to control the pressure of the air within the cylinder 4, a valve member 12 is arranged adjacent the inflating valve 11 whereby pressure may be admitted into the cylinder 4. When the valve 12 is open the air pressure is released allowing piston 5 to descend. The valve His a stand ard inflating valve which automatically holds the air in the cylinder. The valve 12 is a suitabl hand-operated release valve.

The channe ironf13 is provided at each end with a central longitudinal slot 16 in which the connecting members 17 are movably arranged. These connecting members comprise a central web portion having angularly' disposed flanges 18 formed at one edge and provided with additional flanges Y 19 arranged in parallel spaced relation with ne'ctor and provided with an opening 20.

'Connected to this transverse upperend of .7 the tire casing. It

the body of the connector s a transverse bar 21 having a central perforation whereby the same is pivotally connected to the end 22 of the connector by means of the pivot bolt 23. It will be-noted in the construction of this device that one of the connecting memhers is arranged at each end-of the channel iron or othersupport 13 and the cross bars 21 are pivotally connected to the upper ends 22 of the connecting members and pivotally connected to each end of the cross bars 21 are the movable arms 24, the outer ends of which are, provided with curved portions and pivotally connected to the arms 24 adjacent the outer'ends thereof are the hook members 26, said hook members being provided with a bearing surface adapted to bear against the curved portion 25 of the arms 24 as shown in Fig. 2, the curved portions of the arms 24 serving to support the hooks 126 in position and retain them in contact with e object with which they are'engagzd.

operation, the tire casing which is generally indicated. in the drawings by A, is

placed upon the mandrel 7 and the hook members 26 engaged over the beading of will be understood that when the tire A is first placed in position upon the mandrel, the mandrel is in a lowed ered position and when it is desired-to ex pose the interior of the tire casing, air pressure is admitted into the cylinder 4, through the medium of the valves 11 and '12, to force the piston 5 upwardly which in turnimbl parts an upward movement to the mandrel 7 forcing the interior of the tire to the position illustrated in Figs. 1 and 2 where the interior of the tire can be readily inspected and is placed in such a position that repairs can be quickly andeasily made. It

will be apparent that when it is desired to a release the tire casing, the air pressure from the cylinder 4 is released, permittin the mandrel 7 to drop downwardly towar the channel member 13. The hook members 26 can then be readily released from the beadin of the tire and the tire removed.

rom the above description taken in con."- nection with the accompanying drawings, it will be readily apparent that I have rovided a very simple device, constructs of very few parts so that-the same can be readily moved from placefto place, whereby a tire casing can be quickly and readily turned inside out for inspection 'of the interior thereof or for repairing without causing damage to the tire Whatever. wish it to be understood that while I any have shown and described certain means.

for admitting air pressure to the cylinder 4, I do not wish to be limited to this particular type of construction, but desire to I make such changes as may fall within the scolpe of the claims.
